In 1998, Netscape released the source code to its browser and Microsoft's own leaked internal memos, later called the Halloween Documents, admitted that free software posed a real threat to Windows. J.T.S. Moore's film traces how that moment came about, starting with Richard Stallman leaving MIT's AI Lab in the 1980s to build the GNU project after a printer driver dispute convinced him proprietary software was a moral problem, not just a technical one. Linus Torvalds explains how he wrote the Linux kernel as a student in Finland and gave it away, and how it fused with Stallman's GNU tools into a working operating system. Eric Raymond, Bruce Perens, and Larry Augustin describe splitting off the term "open source" from Stallman's "free software," a rebranding meant to make the movement palatable to corporations and investors. Interviews with Netscape and early Linux-company executives sit alongside Stallman's own account of why he still objects to the rebrand. The film lays out the argument in the founders' own words rather than settling it for them.
